Used to list database transaction details as they occur. The transaction log can be useful for isolating the causes of unexpected interactions between ConstructSim Planner and the database. Processing slows significantly, however. Transaction details include SQL statements (generated by ConstructSim Planner or an application or submitted by the user in the SQL Window), ConstructSim Planner database requests, and status and error messages issued by the database software. ConstructSim Planner database requests are listed in UPPERCASE.
